Powered by  a 3.0 Liter BMW TwinPower Turbo engine, the M4 GTS relies on a whopping 493 horsepower and 443 lb-ft of peak torque. The power is harnessed through a 7-speed M Double Clutch Transmission with Drivelogic that allows the M4 GTS to roar from 0 to 60 mph in 3.6 seconds.  In a nutshell, the BMW M4 GTS is a race-bred car that utilizes the best from BMW’s engineering and design departments, creating a track-ready behemoth that’s fully optimized and set up for racing conditions.
Why would you then do anything to a BMW M4 GTS? After all, it’s the pinnacle of engineering and performance available for the M4. On the other hand, many will say why not. That same thought process is what drove Vorsteiner in changing the outer appeal of the M4 GTS by adding aftermarket aero parts and wheels to this beast.
Furthermore, since the BMW M4 GTS is an already aerodynamically sound vehicle, the tuner didn’t go a long way in changing its exterior appeal. The addition of a Vorsteiner rear diffuser and a set of FlowForged wheels fits the M4 GTS perfectly. The rear diffuser adds both a visual and a performance upgrade, helping keep the rear end of the M4 planted to the ground and affording the driver with improved traction.
Another key point of the build are the wheels. The addition of Vorsteiner V-FF 106 wheels makes for a perfect argument towards the switch from the OEM wheels. The V-FF 106 FlowForged wheels are light, good looking and add a nice final touch to the M4 GTS exterior upgrades. The wheels come in sizes of 20×8.5 and 20×10.5 in the front and rear, respectively.
Additionally, the tuning company adorned the wheels with a Carbon Graphite finish. All things considered, the M4 GTS looks good with these parts. Take a look at the finished product, available in the photoshoot added in the media gallery below.
